Pollutants

It is an offense, to pollute the water with things like oil and garbage, fuel, antifreeze and other toxic substances such as cleaning supplies. Biodegradable cleaning supplies are recommended for on-water use. If you have accidentally polluted the water, or see evidence of someone doing so, report it immediately to a Government of Canada pollution prevention officer. Boaters should also be aware of the problem of carrying unwanted species from one area to another (cross-contamination). In some areas of Canada, vessels are prohibited from pumping sewage (also known as blackwater) overboard. When transporting a vessel from one body of water to another, clean the bottom and bilges to prevent spreading unwanted invasive species.
